Smith's fx unsp radius, subs for opn fx type I/2 w nonunion

This code signifies a Smith's fracture, a specific type of distal radius fracture where the distal fragment is displaced volarly (anteriorly), in an unspecified radius. The "subsequent encounter" indicates the patient is receiving follow-up care for an open fracture (Type I or II) that has failed to heal properly, resulting in nonunion.

Use this code when documenting ongoing treatment for a patient with a previously diagnosed open Smith's fracture of the radius (either Type I or II) who is experiencing nonunion. This applies to situations such as cast changes, physical therapy, or surgical intervention aimed at promoting healing after the initial treatment.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for an open fracture.
• Verify the fracture is indeed a Smith's fracture and not another type of distal radius fracture.
• Confirm the open fracture type (I or II) was previously diagnosed and documented.
